由上海建工集团自主研发的地下空间新型非开挖“利器”----国内首台盾构法掘进的土压平衡超大截面(10.1米X 5.3米)矩形盾构机近日在虹桥临空园区10-3、11-3地块地下连接通道工程首推告捷。矩形盾构法隧道作为国内一种全新的施工方法,较传统的圆形盾构,空间利用率提升20%以上,以其高效的地下空间使用率、可浅覆土长距离曲线掘进、掘进施工时对周边环境影响小的特点,填补了国内隧道工程 New Type of Trenchless Excavation for Underground Space Developed by Shanghai Construction Engineering Group - The first earth-pressure balance large cross-section (10.1 m X 5.3 m) Pioneer Park 10-3, 11-3 underground connecting channel project devaluation victory. As a new construction method in China, the rectangular shield tunneling method has a space utilization ratio more than 20% higher than that of a traditional circular shield tunnel. With its efficient utilization of underground space, tunneling can be carried out with long-distance curves of shallow overburden and tunneling Small impact on the surrounding environment features to fill the domestic tunnel project
